Main scripts:
	Replication_main.do
	Replication_appendix.do
	
Data files: 
	data47-125.dta
	data1-46.dta

| General                                   |
+-------------------------------------------+

The main replication script (Replication_main.do) reproduces all results reported in the paper 
'Order Effects, Reciprocity, and Equilibrium Play in a TV Show'. Results are reported 
in the same order as in the main text of the paper.

For weeks 19-46, use data1-46.dta and the Replication_appendix.do file. 
The main analysis focuses on weeks 47-125 where the grading rule strictly requires a minimum 
score of 3 and prohibits evaluators from reusing scores.

Running the scripts requires all data files to be in the working directory.
The scripts were tested with Stata/SE and require standard Stata packages.

+-------------------------------------------+
| Replication_main.do                       |
+-------------------------------------------+

This is the main analysis script that reproduces all results reported in the paper for weeks 47-125.
The script performs the following analyses in sequence:

1. Data Loading and Preparation
   - Loads data47-125.dta
   - Handles missing data and exclusions for incomplete menus, disqualifications, or previous winners

2. Descriptive Statistics
   - Summary statistics for points by treatment and cooking order (Table 1)
   - Distribution analysis of scores assigned by contestants (Table 2, Figure 1)

3. Empirical Analysis
   - Evaluator Fixed Effects estimation (Table 3)
   - Interaction model for cooking order and evaluator status (Table 5, Figure 2)
   - Robustness comparison between Fixed Effects, Hierarchical, and Random Effects models (Table 6)
   - Probability of winning analysis using LPM, logit, and probit models (Table 7)

4. Host Scoring Behavior and Dyadic Reciprocity
   - Analysis of program host evaluations against peer consensus (Table 8)
   - Dyadic reciprocity and strategic robustness test replacing the former Social Relations Model (Table 9)

The script generates tables and figures matching those in the paper.

+-------------------------------------------+
| Replication_appendix.do                   |
+-------------------------------------------+

This script analyzes weeks 19-46 and provides comparative analysis with the main results.
It imports data from data1-46.dta and generates supplementary Tables A3 through A12, as well as Figures A1 through A3 for the appendix. This includes robustness checks for learning effects and time trends.

+-------------------------------------------+
| data47-125.dta                            |
+-------------------------------------------+

This Stata file contains data for weeks 47-125 collected by watching episodes of the TV show "Zuhal Topal'la Sofrada".
The data includes scoring behavior, cooking order, and contestant interactions under the modified grading system introduced in week 47.

+-------------------------------------------+
| data1-46.dta                              |
+-------------------------------------------+

This file contains data for weeks 19-46, representing the earlier period with different grading rules.
Used for comparative analysis in the appendix.

| Variable Definitions                      |
+-------------------------------------------+

Core Variables:
- week: Week identifier (ranges 47-125 for main analysis)
- cook: Cooking order identifier (1-5)
- evaluator: Evaluator identifier (1-5)
- points: Points assigned by evaluator to cook
- total: Total points received from all four evaluators
- host: Points awarded by program host
- overall: Sum of total and host points (final score)

Cooking Order Dummies:
- cook_first: =1 if cook=1 (Monday)
- cook_second: =1 if cook=2 (Tuesday) 
- cook_third: =1 if cook=3 (Wednesday)
- cook_fourth: =1 if cook=4 (Thursday)
- cook_fifth: =1 if cook=5 (Friday)

Control & Strategic Variables:
- i_cook: Cook identifier variable
- already_cooked: =1 if evaluator already cooked before evaluation
- score_received: Points the current contestant previously assigned to the current evaluator (used for reciprocity)
- peer_avg: Average points assigned by the four peer evaluators to a cook
- host_score: Score assigned by the host (constant for that cook)
- learning_interaction: Interaction term between 'already_cooked' and a centered week variable

Exclusion Dummies:
- disqualified: =1 if contestant disqualified in that week
- unfinished_menu: =1 if contestant unable to finish menu
- groom: =1 if groom cooked instead of bride
- previous_winner: =1 if previous winner participated again

| Data Collection                           |
+-------------------------------------------+

The data was collected by systematically watching episodes of the 
Turkish TV show "Zuhal Topal'la Sofrada", which follows a format similar to "Come Dine with Me."
Data Source:
- Episodes 1-625 were watched and coded
- Available on YouTube and the NOW TV website: https://www.nowtv.com.tr/Zuhal-Topal-la-Sofrada/bolumler
- Data collection covers the complete scoring interactions between contestants

+-------------------------------------------+
| Notes                                     |
+-------------------------------------------+

- Evaluator Fixed Effects control for time-invariant differences in grading tendencies. Because evaluators participate in only one competition week, these fixed effects inherently absorb all week-specific heterogeneity.
- Standard errors are clustered at the week level in all regression analyses to account for correlation among evaluators sharing the same strategic environment.
